Chemistry of interstitial waters of ODP Leg 112 samples

Two distinct hydrogeochemical regimes currently dominate the Peruvian continental margin. One, in shallower water (150-450 m) shelf to upper-slope regions, is characterized by interstitial waters with strong positive chloride gradients with depth. The maximum measured value of 1043 mM chloride at Site 680 at ITS corresponds to a degree of seawater evaporation of ~2 times. Major ion chemistry and strontioum isotopic composition of the interstitial waters suggest that a subsurface brine that has a marine origin and is of pre-early Miocene "age," profoundly influences the chemistry and diagenesis of this shelf environment. Site 684 at ~9°S must be closest to the source of this brine, which becomes diluted with seawater and/or interstitial water as it flows southward toward Site 686 at ~13?S (and probably beyond) at a rate of approximately 3 to 4 cm/yr, since early Miocene time. The other regime, in deep water (3000-5000 m) middle to lower-slope regions, is characterized by interstitial waters with steep negative and nonsteady-state chloride gradients with depth. The minimum measured value of 454 mM chloride, at Site 683 at ITS, corresponds to ~20% dilution of seawater chloride The most probably sources of these low-chloride fluids are gas hydrate dissociation and mineral (particularly clay) dehydration reactions. Fluid advection is consistent with (1) the extent of dilution shown in the chloride profiles, (2) the striking nonsteady-state depth profiles of chlorides at Sites 683 and 688 and of 87Sr/86Sr ratios at Site 685, and (3) the temperatures resulting from an average geothermal gradient of 50°C/km and required for clay mineral dehydration reactions. Strontium isotope data reveal two separate fluid regimes in this slope region: a more northerly one at Sites 683 and 685 that is influenced by fluids with a radiogenic continental strontium signature, and a southerly one at Sites 682 and 688 that is influenced by fluids with a nonradiogenic oceanic signatures. Stratigraphically controlled fluid migration seems to prevail in this margin. Because of its special tectonic setting, Site 679 at ITS is geochemically distinct. The interstitial waters are characterized by seawater chloride concentrations to -200 mbsf and deeper by a significantly lower chloride concentration of about two-thirds of the value in seawater, suggesting mixing with a meteoric water source. Regardless of the hydrogeochemical regime, the chemistry and isotopic compositions of the interstitial waters at all sites are markedly modified by diagenesis, particularly by calcite and dolomite crystallization.

Tertiary and Quaternary calcareous nannoplankton biostratigraphy of ODP Leg 112 holes

Positions of all cores recovered during Ocean Drilling Program (ODP) Leg 112 off Peru are shown in the standard calcareous nannoplankton zonation. Stratigraphic and regional occurrences and preservation of calcareous nannoplankton are discussed for all sites, and fossil lists are presented for selected samples. Late Miocene to Holocene nannoplankton assemblages in the upwelling systems off Peru and scattered blooms, especially of Gephyrocapsa species and Helicosphaera carteri, are described. Scyphosphaera assemblages found in late Miocene Zone NN9 {Discoaster hamatus Zone) at Site 684 are compared with similar assemblages from Gabon on the west coast of Africa. Remarkable subsidence is indicated by early and middle Eocene nearshore and shallow-water nannoplankton assemblages for Sites 682, 683, and 688. Besides several local hiatuses, major regional hiatuses were noted at Site 682 (upper Eocene, uppermost middle Eocene, and part of the lower and middle Oligocene missing), Site 683 (uppermost middle Eocene to lower part of the middle Miocene missing), and Site 688 (part of the middle Eocene, uppermost middle Eocene to upper Oligocene, and parts of the lower and middle Miocene missing).

Heat-flow studies in the Peru Trench subduction zone

New heat-flow values were obtained in the central Peru Trench area during site surveys and drilling of Ocean Drilling Program (ODP) Leg 112 by measuring temperatures with ordinary surface heat-flow probes and in the drill holes and by estimating from bottom-simulating reflectors resulting from gas hydrates. The values determined by these methods are consistent with each other within the limits of error. When combined with existing data, heat-flow distribution from the trench to the coast was delineated. Heat flow is lower than 40 mW/m**2 at the bottom of the trench and 40 to 50 mW/m**2 on the landward slope. The low heat flow at the trench bottom can be explained partly by a high sedimentation rate. Heat flow is variable about where the Mendana Fracture Zone meets the trench. This low heat flow might result from hydrothermal circulation in the fracture zone, which some scientists believe is a new propagating rift. On the landward slope, no significant difference in heat flow is recognized between the northern side and the southern side of the fracture zone, in spite of differences in the age of the subducting plate and the tectonic history. Heat flow on the landward slope may be slightly higher than that in most other subduction zones.

Diário da Constituinte [gravação de vídeo] : [programa n. 112]

Os constituintes evangélicos discutem o novo projeto constitucional e querem suas propostas aprovadas na nova Carta. Manoel Moreira (PMDB-SP) almeja uma Constituição que respeite os direitos dos brasileiros e que acabe com a impunidade generalizada no país. As questões que mais preocupam esse grupo são: família, aborto, o casamento e a liberdade de culto. Salatiel Carvalho (PFL-PE) não concorda com alguns pontos aprovados na Comissão das Garantias tais como os direitos e garantias aos homossexuais e a questão do aborto. Na sessão O Povo Pergunta, cidadão pede atenção para a saúde do nordestino. Inocêncio Oliveira (PFL-PE) responde que a Assembleia Nacional Constituinte (ANC) precisa definir uma lei que proporcione o acesso de todos a rede pública de saúde e melhore a distribuição de renda. A Comissão de Sistematização prevê que os recursos públicos serão destinados para escolas públicas, comunitárias, filantrópicas e confessionais. Agripino Lima (PFL-SP) considera que as verbas públicas devem ser destinadas as escolas públicas, voltadas ao ensino fundamental. Ubiratan Aguiar (PMDB-CE) diz que os recursos são insuficientes e que a educação pública não pode dispersar suas verbas para as escolas particulares. Átila Lira (PFL-PI) acredita no avanço da educação pública e de melhores condições de trabalho para o professor.

El derecho de información del socio en la S.A. y en la S.R.L. Arts. 112 LSA y 51 LSRL

Este árticulo explica que el derecho de la información es uno de los denominados derechos individuales del accionista o socio, que se deriva de la titularidad de acciones o participaciones, derecho fundamental e inherente a la condición de socio, e inderogable, que se ostenta por normas imperativas que reconocen dicho derecho. Contribuye a un mayor control y participación del socio en la marcha de la sociedad ya que trata de facilitar a los socios un conocimiento directo sobre la situación y gestión social constituyendo, por tanto, uno de los más importantes derechos del mismo.

Welt-Fischereierträge 1995: 112,9 Mio. Tonnen

Total world fishery production 1995, including aquaculture, of fish, shellfish, frogs and turtles – reached a new record of 112.9 million tones live weight. Marine fishery had a share of 91,9 million tonnes (+ 0.4) and freshwater fishery 21.0 million tonnes (+ 2.0). Not included in these figures are seals, whales, crocodiles and algae. Marine mammals and crocodiles are listed by number of killed individuals, and not given by weight. Algae alone represent a biomass of 7.1 million tonnes, but are not included by the FAO in the nominal „total production of the world“ either. About two thirds of the marine fishery harvest was used for human consumption, one third for industrial purposes – mainly production of fish meal and fish oil.

Diseño y desarrollo de una aplicación de 112 de nueva generación

[ES]Este proyecto trata acerca de diseñar y desarrollar una nueva aplicación de 112 de nueva generación. Para ello, se realiza un estudio de todas las alternativas posibles y se establece como objetivo la creación de una aplicación que se base en las redes de nueva generación, más conocidas como NGN. Esta aplicación se conectará con los servicios de emergencia (ambulancias, bomberos, policía…), proporcionando la localización del usuario y, en base a ello, contactar con el servicio más cercano posible. Además, se trata de comprobar si las nuevas tecnologías emergentes pueden ser utilizadas cualquier otro fin.
